news - 26 Jan 2005 18:03 GMT I have seen your website under 300ZX information. First, thanks for posting. You said use "Nissan" air filter. Is Fram air filter as good as Nissan air filter? I have to buy a new one and wondering if Fram air filter from WalMart is acceptable.

Seeing the number of people with cone filters asking about running problems (look like dead AFM) and having had problems (looked just like a dead AFM) myself just by leaving lower air box clips undone (took 4 weeks to find, even a search for leaks using damp start ether didn't find it), I can say that the AFM is very sensitive to turbulence in the inlet. A lower grade fliter may not distribute the air evenly enough and will appear to have killed the AFM. New/exchange AFM and OEM Nissan filter will fix it.

Because you can see they are full of dirt. Many times the rubber seals fall apart and I find pieces of leaves etc inside the meter.

I always try a filter first, never seen it fix the problem. I know you think these meters NEVER fail, but it's a very comon problem. What kills them with a cone filter is when they are over oiled and the oil residue get's burned onto the wire.
BTW you still haven't taken me up on buying the dead meters I have that you claim there is nothing wrong with, say $50 each sound fair?

Not when they buy new nissan ones. So you ready to buy a dozen or so at $50 a pop? Since they never go bad as you claim, you should be able to sell them for $200 each and make some money huh? Let me know, I accept paypal when you're ready.

Unless you want to gamble with trashing a $500 MAS to save $10 on a filter you replace every 30,000 miles..

Good grief, are you THAT cheap?

A real one is $10 !!!! How much do you expect to save? Maybe enough to buy a couple of kristal burgers? You'd have to go through 150 of them to save enough to pay for =ONE= MAS sensor!
Same with the oil filters, they are less than $6 and everyone is trying to use $4 ones instead? Yea that's a HUGE savings and worth risking a $3000-$10,000+ engine on. I never understood this logic.

iRateRides Customer Service - 29 Jan 2005 21:22 GMT If I could add my 2 cents, I would suggest the K&N air filter. You can find them on my site here http://www.iraterides.com/sportcompact/store/viewitem.asp?idProduct=14621&idMode l=3424#AppChrt Many of my competitors also carry them.

It costs 4 times what a real nissan filter costs, still requires cleaning (take a while in case you've never done it + special oil etc) and breaks even money wise after 120,000 miles of use. And then you still have to worry about oil contamination of the MAS. Whoops it trashed the sensor, pay $500 please...

none - 29 Jan 2005 22:51 GMT I had K/N on my GM cars and I have removed it. Would not even consider it if someone give it to me for free. In fact, I have two that I would like to sell at fraction of the cost I paid for it. K/N does not improve power and if it is, it is so small that you can even quantify it. Like Steve said, MAS is expensive to replace but most of all, you can be stranded.

Steve T - 31 Jan 2005 03:28 GMT > Anyone ever woundered who makes the filters for Nissan? > I'll give you a clue it ain't Nissan................ Sure nissan doesn't make them themselves. But for $10 a filter, how much time are you going to waste trying to figure where to buy them to save what, 2-3 bucks? And if you guess wrong (or they aren't to the same specs), it's RUINS a $500 part. If these filters were $35+ and the others sold for $3 MAYBE I could see it. But that isn't the case.
It's the same with oil filters. You can buy REAL nissan ones for $5 and the cheap replacements that may or may not be the right thing are $3 so you save enough to buy a big mac and risk throwing away several thousands of dollars in engine repairs. That's NOT being very smart.

That's NOT being very smart. The good oil filters (for the VG30DE(TT) engine) are not being sold by nissan anymore. You're stuck with someone that still sells the old filter, and/or a filter that's been cut open and analysed to be equivalent to the old nissan filter. Have a look around on twinturbo.net and find out for yourselves.

The 55Y00 is better than ANY of the aftermarket junk and I'd go with nissan if they say it's OK to use them.

David Riggs - 12 Feb 2005 10:03 GMT Something you might check:
Nissan had a problem with faulty connectors to the throttle position sensor, but didn't publicize it much because they wanted to avoid a recall. Their field service engineer told me about it when I was seeing a slight loss of power as well as high/oscillating idling. His recommendation was to cut out the old connector and replace it with one of more reliable design. Its been a while, so I don't remember if it is 3 or 4 wires, but I used a 4-pin microphone connector male/female pair. These are often used by radio amateurs and come up to 8 or 9 pins which are arranged in a circle around a central cylinder. The male & female fasten together with a threaded collar, so it makes a good secure connection. Radio Shack sells them. Once I soldered both halves together, I covered the exposed ends where the solder lugs are with bondo. Now my Z idles perfectly at 1000 RPM, never misses and purrs.
One of the other "non publicized" problems was with the radiators. The side tanks are sealed with o-rings, which become less pliable at cold temps. They had a lot of complaints where coolant leaked out only when the engine was cold. When customers took them in for service, the radiators tested good because the engines had been running and warmed them up. So it was easy to convince the owner that it was all "in their heads."
Give it a try, Dave
